Can I make changes to a pending reservation request?

In general, it is possible to make changes to a pending reservation request, but it depends on the policies of the specific reservation system or service that you are using. It is recommended that you check the terms and conditions of your reservation, and contact the service provider or booking agent as soon as possible to make any necessary changes. Some reservation systems may allow changes to be made directly online, while others may require you to contact customer service or submit a new request. Keep in mind that there may be fees or restrictions associated with making changes to your reservation, so it’s best to review the policies carefully before making any changes.
